Targeted and untargeted analyses of the sub-5 kDa urine metabolome of genitourinary cancer patients (prostate and/or bladder) were performed without chemical derivatization using capillary electrophoresis-electrospray ionization-mass spectrometry (CE-ESI-MS). For targeted analysis, endogenous levels of sarcosine and 5 other amino acid metabolites implicated in the progression of prostate cancer were quantified in four patients and in a pooled urine sample from healthy volunteers. An untargeted analysis (m/z 50 to 850) of patient urine was performed using the same CE-ESI-MS system identifying over 400 distinct molecular features per patient...

BACKGROUND: Identification of the lymphatic system in cadavers is painstaking because lymphatic vessels have very thin walls and are transparent. Selection of appropriate contrast agents is a key factor for successfully visualizing the lymphatics. In this study, we introduce a new imaging technique of lymphatic mapping in whole body of fresh cadavers. METHODS: Ten fresh human cadavers were used for this study. We injected 0.1 mL of indocyanine green fluorescence (ICG) solution subcutaneously at multiple spots along the watershed lines between lymphatic territories and hand and foot regions...

BACKGROUND: The European Paediatric Regulation was introduced in 2007 to facilitate access to new medicines for children. Our study explored accessibility of early-phase trials in pediatric oncology, in line with the European Paediatric Regulation, to identify the reasons for not inviting patients to participate, parents' refusal, or inclusion failure. PROCEDURE: We conducted a retrospective chart review at Institut Curie, Paris, for all pediatric patients whose cancer progressed despite known effective treatments between July 2010 and December 2013...

A 43-year-old men was found an esophageal submucosal mass at 26 cm from the incisors; and preoperative EUS suggested a leiomyoma in MP layer. STER1, 2 , deriving from POEM3, 4 , was performed, and an inverse T incision5 was carried out firstly. Subsequently, a submucosal tunnel was established extending to the distal esophagus; and a mass, covered with MP tissue, was discovered (Figure 1); particularly, the mass was going up and down rhythmically, and had soft touch; given the possibility of aorta compression or cyst, ECDUS was conducted and uncovered a homogeneous hypoechoic lesion, just against thoracic aorta (Figure 2)...

Education plays a crucial role in the lives of families of transgender young people and mental healthcare practitioners are well-placed to support families in this regard. This paper reports findings from a narrative review of 31 papers that explored the education needs of families of transgender young people. The emergent themes were synthesised to develop a five-stage model that depicts the role of education in the lives of these families. Key themes included: (i) learning that a family member is trans; (ii) family responses; (iii) accessing education and information; (iv) impact on the individual; and (iv) moving beyond the individual...

In-cell NMR of macromolecules has gained momentum over the last ten years as an approach that might bridge the branches of cell biology and structural biology. In this review, we put it in the context of earlier efforts that aimed to characterize by NMR the cellular environment of live cells and their intracellular metabolites. Although technical aspects distinguish these earlier in vivo NMR studies and the more recent in cell NMR efforts to characterize macromolecules in a cellular environment, we believe that both share major concerns ranging from sensitivity and line broadening to cell viability...

Background and objectives: Slowed and curved rapid eye movements, saccades, are the well-known features of progressive supranuclear palsy (PSP). We hypothesized that the saccades in PSP are not only slow and curved, but they are also irregular and have timing deficits. Methods: We tested this hypothesis in 12 patients with PSP by measuring vertical and horizontal visually guided saccades using a limbus tracker. Results: Both, horizontal and vertical saccades were slow and had irregular trajectory and velocity profiles, but deficits were much more robust in vertical saccades...

Segmentation of prostate Cone Beam CT (CBCT) images is an essential step towards real-time adaptive radiotherapy (ART). It is challenging for Calypso patients, as more artifacts generated by the beacon transponders are present on the images. We herein propose a novel wavelet-based segmentation algorithm for rectum, bladder, and prostate of CBCT images with implanted Calypso transponders. For a given CBCT, a Moving Window-Based Double Haar (MWDH) transformation is applied first to obtain the wavelet coefficients...

The global expansion of energy demands combined with abundant rainfall, large water volumes and high flow in tropical rivers have led to an unprecedented expansion of dam constructions in the Amazon. This expansion generates an urgent need for refined approaches to river management; specifically a move away from decision-making governed by overly generalized guidelines. For the first time we quantify direct impacts of hydropower reservoir establishment on an Amazon fresh water turtle. We conducted surveys along 150 km of rivers upstream of a new dam construction during the low water months that correspond to the nesting season of Podocnemis unifilis in the study area...

Quantitative approaches to measure and assess resilience are needed to bridge gaps between science, policy and management. In this paper, we revisit definitions of resilience and suggest a quantitative framework for assessing ecological resilience sensu Holling (1973). Ecological resilience as an emergent ecosystem phenomenon can be decomposed into complementary attributes (scales, adaptive capacity, thresholds and alternative regimes) that embrace the complexity inherent to ecosystems. Quantifying these attributes simultaneously provides opportunities to move from the assessment of specific resilience within an ecosystem towards a broader measurement of its general resilience...

Measurement of urine albumin is important for detecting and monitoring kidney disease. At the present time, measurement of urine albumin is not standardized due to the lack of a reference system, which includes both a reference measurement procedure and certified reference materials. Developing a reference system will provide a means for clinical laboratory measurement procedures to become standardized and will enable successful use of uniform clinical decision points. Currently, urine albumin results vary in excess of 40% depending on which commercially available measurement procedure is utilized for measurement...

Yan Xi, Wenxiang Cong, Daniel Harrison, Ge Wang
In medical X-ray Computed Tomography (CT), the use of two distinct X-ray source spectra (energies) allows dose-reduction and material discrimination relative to that achieved with only one source spectrum. Existing dual-energy CT methods include source kVp-switching, double-layer detection, dual-source gantry, and two-pass scanning. Each method suffers either from strong spectral correlation or patient-motion artifacts. To simultaneously address these problems, we propose to improve CT data acquisition with the Grating Oriented Line-wise Filtration (GOLF) method, a novel X-ray filter that is placed between the source and patient...

Superficial digital flexor tendon (SDFT) of the bovine hindlimb originates from the caudolateral aspect of the distal femur and finally inserts onto the plantar aspect of the middle phalanges. In the present study, morphology and morphometry of the bovine SDFT at the muscle-tendon junction (MTJ), middle metatarsus (mM) and tendon-bone interface (TBI) were investigated. Cross-sectional morphology at the three regions of SDFT were oval, semioval and ring-formed, respectively. Significant difference in cross-sectional area was found only between MTJ-mM and mM-TBI (P<0...

INTRODUCTION: Families are significantly impacted by addictions and family involvement in treatment can reduce the harms and can also improve treatment entry, treatment completion and treatment outcomes for the individual coping with an addiction. Although the benefits of family-focused practices in addictions have been documented, services continue to have an individual focus and research on this topic is also limited. The objective of this study is to map the extent, range and nature of evidence available examining family interventions in addictions and identify gaps to guide future research, policy and practice...

In order to optimally refine the multiple emerging drug targets for hepatitis B virus (HBV), it is vital to evaluate virological and immunological changes at the site of infection. Traditionally liver biopsy has been the mainstay of HBV disease assessment, but with the emergence of non-invasive markers of liver fibrosis, there has been a move away from tissue sampling. Here we argue that liver biopsy remains an important tool, not only for the clinical assessment of HBV but also for research progress and evaluation of novel agents...
